You don't need to charge for a specific time before using it the first time, just start using it and charge whenever the battery indicator appears low, you can't overcharge or damage the battery if you do not charge to a full charge. Charging automatically stops when your battery is full. Lithium batteries, like in your phone, have no memory effect.
